AMD GPU PCs

AMD GPUs are not quite as feature rich as their NVIDIA counterparts, but that's improving rapidly and with their new FSR3 they have almost bridged the gap.  You should still go with NVIDIA if you care about ray tracing though.

Where AMD win out is in pure rasterization which gives you more frames per second in native mode (no frame generation or up-scaling). 

AMD also win out in the value proposition, giving you more frames per £.
